I don't think that's the intention of what he says. The film definitely hints at Bane having a soft spot for the innocent, and while he would indeed be killing a ton of children, in his mind, he's saving future children from the decadence of modern western culture. Hence "For the sake of your children, indeed I hope it does." Interesting that it could also be taken as a threat, though, never thought of it that way.
